01 — Project Overview

What the System Measures

The Automated Lens Metrology System is a fully integrated hardware and software platform designed to characterize optical lenses without manual intervention. A coordinated fleet of sensors — optical, mechanical, and spectroscopic — captures raw measurements that are automatically processed to populate a standardized datasheet.

Each lens inserted into the system undergoes a complete measurement sweep. Geometric properties are extracted via precision mechanical gauging and interferometry, while spectral properties are measured using broadband illumination and calibrated detector arrays across user-defined wavelength bands.

Derived parameters such as effective focal length are computed from the raw measurements and cross-validated against theoretical models, ensuring high-confidence output for research and manufacturing quality-control workflows.
